Abstract
A method for controlling movement of travelling carriers includes performing data communication between front and rear adjacent travelling carriers, an on-board communication device provided to the travelling carrier and performing data communication with a ground-based communication device, and the ground-based communication device sending a movement permission signal at one end of a work area to the on-board communication device of a passing travelling carrier; and transmitting the movement permission signal to all of the travelling carriers within the work area from the ground-based communication device via the on-board communication device and the data communication means.
